Specification of Letters Patent.

Application filed June 10, 1910. Serial No. 566,232.

T 0 all whom it may concern:

Be it known that I, lVInrano H. BU'roi-inn, a citizen of the UnitedStates of America, residing at Burwell, in the county of Garfield andState of Nebraska, have invented new and useful Improvements in Water-Boilers, of which the following is a specification.

This invention relates to water boilers and particularly to one designedfor attachment toa stove pipe, the object being to utilize the heat forthoroughly heating the walls of the boiler suilicientl y on thedischarge of the waste heat products.

Another object of the invention is to provide a boiler of this typewherein the bottom is of substantially frusto-conical form presenting aconcavity which when the boiler is operatively positioned on the stovepipe will be located immediately over the stove and positioned toreceive the best bcnclit of the heat.

Another object of the invention is to provide a boiler having asubstantially funnelshaped top facilitating the filling of the boilerwith. water.

In the drawing, forming a portion of this specification and in whichlike numerals of reference indicate similar parts in the several views:Figure 1 is a detail vertical section through my improved boilershowing it applied to a stove pipe. Fig. 2 is a detail. top plan thereofshowing the stove pipe in section. Fig. is a detail vertical sectionthrough a portion of the boiler showing a slightly modified form of myinvention. Fig. 4 is a horizontal section showing a still furthermodified form.

My improved boiler consists of a casing 1 and 2, the said casing beingapertured centrally for receiving the stove pipe A. The walls 1 of thecasing have their ends extended beyond the top and bottom portions 3 and4, and as illustrated, such portions carry clamping screws or similarequivalent well known devices for engaging the stove pipe to hold theboiler operatively positioned thereon. The bottom l of the boiler is offrusto-conical form presenting a relatively broad or large concavity 5which when the boiler is operatively associated on the pipe willbedisposed at such point with respect to the stove to best utilize thefull value of 1 suitable draw-off click 7.

' the wasteheat, the said concavity forming a. collector for the heatand the walls of the said bottom by being arranged, as shown, form acontracted lower portion 6 in the chamber, thus subjecting the water atthis I point of the boiler to a great amount of heat. At the bottom theboiler is rovided with a 'I he top 3 of the boiler is formedsubstantially throughout to provide an annular concavity 8 which opensdirectly into the boiler, as illustrated. The construction of the boileris such that its top is of substantially funnel form facilitatingfilling the boiler with water as is obvious. The opening in the bottomof the top 3 is closed by a suitable removable plug 9. i In the modifiedform of my invention shown in Fig. 3, the opening 10 in the top 3 3 isclosed by a spring-controlled valve 11. The top supports a spider 12throu h which the guide stem 13 extends, a relative y light spring beinginterposed between the l spider and the said valve 11 and suitably iconnected with the latter to normally in a closed position. Under weightl of the water when the same is poured in the said substantiallyfunnel-shaped top of the boiler the valve will be automatically opened.

In the form of my invention shown in Fig. 4., the boiler is formed oftwo parts 14 and 15, each part being substantially identical. inconstruction and formed with an inner wall 16 and an outer wall 17. Theinner walls are formed with the concavities 18 whose walls will fit thestove pipe. The seei tion 15 is formed with a clasp 19 to engage akeeper 20 on the section 14: so as to he 6. both sections operativelyassociated on the f pipe. Each section is provided with a suitabledraw-othcock 21. \Vith other respects 1 the modified form of myinvention last described is identical with the preferred form ,andfurther detail description is believed unwarranted. The boilerconstructed on lines as described while being useful for domesticpurposes will be found most efiicient in barber shops where it isdesired to obtain small quantities of water for shaving cups or likepurposes.
